| 20100008079 | LED INSPECTION LAMP AND LED SPOTLIGHT - An LED inspection lamp has plurality of LED sources for emitting electromagnetic radiation at different peak wavelengths for causing visible fluorescence in different leak detection dyes. A lens is associated with each LED. Radiation passing through lenses is superimposed in target area at target distance. Another LED inspection lamp has plurality of LEDs emitting electromagnetic radiation at a peak wavelength. A lens adaptor has lens housing for attachment to LED inspection lamp with a single LED for causing visible fluorescence, and a lens. Substantially all of the radiation from the LED passes through the lens and is focused in a target area at a target distance from the lenses. LED spot lights have a similar configuration. The LEDs may produce white light from distinct LEDs or from white LEDs. The light may be a flashlight or fixed spot light. | 01-14-2010 |

| 20090147519 | LED work light - An LED work light has multichip LEDs and a diffusing dome. Each LED may have separate electrical terminals for each chip. The LED work light may have convex lenses forward of each LED. Convex lenses may be hemispherical. Convex lenses may have a nonhemispheric curved surface whose cross section has at least one circular arc and no non-circular arcs. The LED work light has a battery or receives power from an external power source. The LED work light may have a transparent plastic tube as a structural member. A replaceable plastic cover may be added to protect any structural tube or other major transparent part of the LED work light from abrasions. The plastic cover may be tubular. The plastic cover may comprise laminations of plastic that can be removed individually after being abraded. Any external power source may be a wall transformer type and may have current limiting means. The LEDs may be attached to the rear surface of an LED PCB that is fastened to a heatsink in a manner achieving thermal contact between the rear surfaces of the LEDs and the heatsink. A position sensing switch may be used. | 06-11-2009 |
| 20090161351 | LED LAMPS AND LED DRIVER CIRCUITS FOR THE SAME - LED lamp has LEDs aimed rearwards with either a concave mirror to the rear of each LED, or one concave mirror to the rear of two or more LEDs, collecting the light from the LEDs to form a forward projecting beam. LEDs may be high power types that require heatsinking. LED lamp may have a lens forward of each LED to collimate the radiation produced by the LEDs into a beam, where at least one lens has at least one aspheric curved surface. LED lamp may have a transparent reflective optic to collimate the radiation produced by each LED into a beam. For an inspection lamp, the LEDs typically have a peak wavelength of 395 to 415 nanometers for seeing the area being irradiated but not so visible as to overwhelm fluorescence of fluorescent materials to be detected. Other wavelengths may be used. LED inspection lamp has a combination of LEDs of different wavelengths or a combination of at least one LED and at least one other light source such that the lamp produces radiation suitable for detection of materials to be detected and adequately illuminates the area being irradiated. LED lamp has LEDs that produce a beam of suitable radiation with a width of 10 degrees or less without additional optics. LED inspection lamp has head attached to a flexible member, with head serving as heatsink for one or more high power LEDs. Current regulator circuits are also disclosed. | 06-25-2009 |
| 20090183516 | INSPECTION PORT - A manifold gauge set has at least one sight glass window for viewing contents of a refrigeration system or an air conditioning system being serviced. The window may be non-planar to achieve an appearance that varies with the presence or absence of liquid. Such a non-planar window may be in the form of a dome, prism or a fresnel lens. The gauge set may have a second light transmissive window to allow light to illuminate system contents being viewed. A light source may be provided to illuminate system contents being viewed. The light source may provide light through the same window that is used for viewing contents. A diffuser may be provided with a second window to achieve an illuminated background for viewing system contents. Similar configurations may be used in standalone sight glasses, vacuum pumps, and recovery machines. | 07-23-2009 |
| 20100008082 | LED work light - A light comprising an LED whose light intensity decreases as the angle from an axis of the LED increases, and a convex lens associated with the LED such that a beam width of the LED is concentrated by the lens into a narrower beam width, wherein the convex lens includes both a convex surface and a concave surface, and the concave surface is curved more sharply towards its edge than towards its center such that light is more evenly spread across the beam width of the lens. | 01-14-2010 |

| 20080305526 | Melibiose Operon Expression System - New vectors expressible in a host comprising the promoter region of the melibiose operon operably linked to a transcriptional unit that includes nucleic acid sequence which is heterologous to the host. The expression of the nucleic acid sequence is controlled by the promoter region of the melibiose operon. The new vector can be used for the regulated heterologous expression of a nucleic acid sequence in a prokaryotic host. There is an isolated and purified nucleic acid sequence expressible in a host comprising the promoter region of the melibiose operon operably linked to a transcriptional unit that includes a nucleic acid sequence which is heterologous to the host. The expression of the nucleic acid sequence is controlled by the promoter region of the melibiose operon. A prokaryotic host is transformed with the vector or the isolated and purified nucleic acid sequence. There is a method for producing a polypeptide in a host using the vector. | 12-11-2008 |

| 20090078689 | Method of Welding a Wear Layer onto a Parent Material Using a Plurality of Flux-Cored Wire Electrodes, Metal Powder and Welding Powder - A method of welding a wear layer onto a parent material, wherein a welding current is applied to a first wire electrode and to at least one second wire electrode. The first wire electrode and at least one second wire electrode are continuously fed to the parent material for producing a common weld pool. Metal powder and welding powder are fed to the weld pool. The wire electrodes are flux-cored wire electrodes, having a core and a covered electrode. The flux-cored wire electrodes have a higher alloy than a weld deposit analysis of the wear layer to be welded on the parent material. The covered electrode of the flux-cored wire electrodes includes an alloy, which has magnetization properties suitable for adhesion of the metal powder. | 03-26-2009 |
